Question

During ___ , homologous chromosomes separate and dyads move to opposite poles of the spindle.

• A. Prophase I
• B. Anaphase II
• C. Metaphase I
• D. Anaphase I

Answer 1

The correct option is D Anaphase I

During anaphase I, the two chromosomes of each bivalent (tetrad) separate and start moving toward opposite poles of the cell as a result of the action of the spindle.
In anaphase I the sister chromatids remain attached at their centromeres and move together toward the poles.
